Dear community,

We have trouble to connect to a 5G SA n78 private network,
Our devices is based on RM520N GL, using old firmware :
RM520NGLAAR01A06M4G_01.200.01.200

No 5G SA network are discovered when using AT+COPS or AT+QSCAN=2, despite the network and SIM are properly working on 2 different other devices (a modem from another brand, and a smartphone)

Do you confirm it requires absolutely firmware upgrade ?

Is there an alternative by forcing a configuration ?

Best regards
